CURTAN FASTENER.

Application tiled July 18,

To all whom t may concern.'

Be it known that Ross L. BENSON, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,has invented new and useful lmprovements in Curtain Fasteners, of whichthe following is a specification.

It is the purpose of the present invention to provide a fastener orcurtains which are used onautomobiles and other vehicles, the fastenerincluding tensioned jaws adapted to spread when fitting over the head ofa stud (either carried by another curtain or upon a stationary part ofthe vehicle) and to con-- tract after passing over the head in order toengage a groove in the stud, thereby holding the curtain securely.

Another purpose is to provide a fastener of this character dispensingwith the form of fastener now in use.

Still another purpose is the provision of supporting and guiding meansfor the tensioned jaws to hold them in alinement and to guide them inregistration after spreading to insure the jaws contracting and engagingthe jaws on the stud.

A further purpose is the provision of improved means for securing thefastener permanently to the curtain.

A still further purpose is the provision ot curved counter sinks uponthe opposite jaws 'for the purpose of guiding the stud between the jaws,in fact, to permit the stud to more easily enter between the jaws.

Another purpose is the provision ot an improved housing` for the jawsand for the tensioning meansY in order to prevent displacement of suchparts.

lt is to be understood that the particulars herein given are in no waylimitative and that` while still keeping within the scope of theinvention` anv desired modifications et detail and desired proportionsmay be made in the vapparatus according to the circumstances.

The invention comprises further features and combinations of parts to behereinafter set forth, shown in the drawings and claimed.

fin the drawings:

Figure 1 is a view showing the fastener as applied to a curtain and inturn connected to an adjacent curtain to hold the two curtains together,the stud inlthis instance being riveted to the vehicle cover andprovided with double grooves.

plied to a curtain and engaged with a stud which is threaded to astationary part of the vehicle.

Figure 3 is a cross sectional View on line 8 8 of Figure 1.

Figure 4 is a cross sectional view on line 4.-4 of Figure 3.

Figure 5 is a sectional view on line 55 of Figure 4.

Figure 6 is a sectional view on line 6-6 of Figure 4.

Figures 7, 8 and 9 are detail views of the studs 4, 5 and 6 which areused for fastening curtains together or to a stationary part of thevehicle.

Figure 10 is an enlarged detail edge view of the cover plate 18.

A Referring to the drawings, 1 designates the main part of the casingwhich is chambered, as shown at 2, to provide a housing for thetensioned jaws 3 which cooperate with various studs 4, 5 or 6, as shownin the detail views in Figures 7, 8 and 9.

1n constructing the main part of the housing 1, a marginal flange 7 isprovided. At diametrically opposite portions of the housing, the iiange7 is relatively thin and its edge is provided with a rabbet 8. Theflange at right angles to the relatively thin portions is provided withdiametrically enlarged or thickened solid parts 9. The adjacent corneredges oi' these parts 9 are rabbeted, as at 10, and these rabbets mergeinto the rabbet 8 of the relatively thin portions of the flange. Theralobet 8 and the rabbets 10 receive a plate 11 which corresponds to theshape of the chamber 2 of the main part of the casing.

Extending from the bottom wall of the chamber 2 and disposed adjacent tothe diametrically opposite sides of the bottom are posts 13. The postsare diamond-shaped in cross section and their ends, as shown, haverabbets 14. The rabb'eted ends of the posts 13 enter correspondinglyshaped openings 15 in the plate 11. The posts 13 have bores orcylindrical chambers 16 which receive projections 17 which projectlaterally from a holding plate 18. This plate is circular and is usedfor securing the fastener to a curtain. In other words, the curtain isplaced between the plate 18 and the main body 1 of the fastener. thatis. after disposing the plate 11 in position in the rabbets 8 and 10 andin engagement with the posts 13. The projections 1? ierce or penetratethe curtain and enter the ores or chambers 16 or the posts, therebyassisting materially in alfording a secure means for connecting thefastener to the curtain. v Y

The diametrically oppositie enlargements or solid portions 9 of the mainbody 1 of the fastener' have bores 19 of cylindrical form and the innerends of the bores are curved, as shown clearly in Figure 6, and areadapted to receive the pointed projections 2O which are also carried bythe plate 18. The pointed projections 20 likewise pierce or penetratethe curtain and act as means to additionally secure the fastener to thecurtain.

When the plate 18 is placed in position, after the projections 17 and 20have pierced or penetrated the Y curtain, the plate 1s pressed asclosely as possible toward the main part 1 of the fastener. ln otherwords, the plate 18 can be disposed so that t-he projections 2O willcontact with the larger curved wall of the inner curved ends of thebores 19. When the projections 20 are so arranged, the plate 18 isforced toward the main part 1 of the fastener by heavy pressure or byhammer blows 0r the plate 18 positioned as closely as possible to themain part 1 of the fastener may be placed between the jaws of a vise toforce the plate 18 tightly against the main part 1 of the fastener. Inforcing the plate 18 in such position, the inner pointed ends of theprojections 20 will cam upon the larger curved wall of the inner curvedends of the bores, causing the projections 20 to bend and therebyconform to the inner curved ends of the bores in such a manner as toanchor the plate 18 so securely in position as to prevent displacementof the plate. In this way, the fastener is connected securely tothecurtain, the projections 20 acting as additional means forpreventing` displacement of the fastener.

The jaws 3 have annular grooves 21 in which a round coiled spring 22engages. This spring acts to draw the two jaws 3 together and, due toadjacent edges of the jaws having semi-diamond-shaped recesses 23,engaging the posts 13, the jaws are guidedtoward and in register witheach other. The semi-diamond-shaped recesses 28, when the jaws 3 are inregister, cause diamond-shaped openings to be formed forV the receptionof the diamond-shaped posts which project from the bottom of the chamberof the main body 1 of the fastener. When the jaws separate against thetension of the spring 22, the faces of the posts cooperate with therecesses 23 to guide the jaws in register and to hold them in position.

The jaws 3 also have semi-cylindrical recesses 24- on their adjacentedges and when such recesses 24 are in register a cylindrical openingisafforded for the reception of one nseaeea of the posts f1, 5 or 6. Themarginal surface adjacent the ends of the recesses 24 are curved off, asshown at 25, or, in other words, counter-sinks are provided acting tocause one of the studs 4, 5 or 6 to more easily enter Vthe centralopening caused to be formed by the recesses 24. A'l/Vhen either one ofthe posts 4, 5 or 6 enters the central opening between the jaws 3, thejaws spread, and after spreading over the heads 26 of the posts or overthe intermediate enlargement 27 of the post 6,'the jaws diametricallycontract for theV purpose'of engaging one or the other of the annulargrooves 28, 29 or 30. Y

When the openings made bythe recesses 24 engage with either one of thegrooves of said posts, a curtain is held connected to another curtain orto a stationary part of the frame of the vehicle. This form of fastenerwill hold the curtain securely and the construction of fastener as aboveset forth dispenses with the form of fastener now in use which Vissomewhat similar in` construction to the extensively used glove snapfastener. 1n such construction of fastener there are no eXpansible orspreading jaws which enable the fastener to be more easily connected toa post. The central opening between the jaws 3, due to the countersinksor post guiding surfaces, is contracted near its central portion so asto correspond with andfit any one of the grooves 28. 29 or 30.

The plate 11 has a central opening 31 corresponding to the largerdiameter of the countersinlrs or curved portions 25 of the jaws. Theplate 18 also has an opening 32 whichcorresponds in diameter to theopening 31. Thes'eopenings enable any one of the studs to penetratebetween the jaws for thedpurpose of securing the fastener to a stu Theinvention having been set forth, what is claimed is:

1. A fastener for curtains includin a main body having a chamber, aplate c osingthe chamber on one side of the main body,1tensionedspreading jaws in the chamber, posts projecting from the bottom of thechamber anddisposed between'the jaws for guiding them in register, saidjaws having opposite recesses forming an opening to receive a stud on acurtain or a stationary part of a vehicle, a plate between which and themain body a curtain is' disposed, the second plate having projectionspassing through the curtain and entering the posts to secure said parts,and means carried by the second plate and operatively connecting withthe main body of the fastener for securing the second plate in positionand securing the fastener to the curtain.
